Alien303 is designed to streamline the creation of psytrance basslines, offering a unique approach inspired by the classic 303 concept. Unlike traditional models, Alien303 expands the sonic palette with a range of digital and virtual analog oscillators, delivering sharp and robust tones that stand out in electronic music production. Its sound character is distinctly digital yet organic, providing an edge that suits modern psytrance and related genres.

The plugin features a variety of oscillator types that contribute to its rich sound spectrum, including analog saws, ramps, squares, and pulses. This variety enables producers to craft basslines with different textures and complexities. Complementing the oscillators is a vintage-style virtual analog filter that offers resonance for shaping the sound with precision and warmth, adding depth and clarity to the basslines.

Alien303 also includes effects and modulation options such as a unison/chorus effect, non-linear saturation, and a ping-pong stereo delay, enhancing the spatial and harmonic qualities of the sound. Additional features like amp and filter envelopes along with portamento allow for expressive playing and dynamic bass movement. These elements combine to create a powerful tool for producers aiming to achieve cutting-edge psytrance bass sounds.
